A food web is a system of interlocking and interdependent food chains. In each food web there are several trophic levels. The trophic level of an organism is the position it occupies in the food chain. These trophic levels include: primary producers, primary consumers, secondary consumers and tertiary consumers.

Coral reef growth or lack of growth is considered an indicator of water health. Coral reefs can be damaged by industrial waste and human sewage. The dumping of herbicides and pesticides into the water can poison and destroy coral reefs as well.

NEWS DEEPLY Thank You, Deeply Dear Deeply Readers, We want to let you know that Oceans Deeply will be pausing publication on September 1. We have loved serving our community with great journalism and informed conversation, but for the time being financial support for the platform has come to a close. We will continue to produce events and special projects while we explore where the on-site journalism goes next.

If you’d like to support continued reporting on Oceans Deeply or collaborate on producing research or events that help fund our journalism you can reach us at. All the Best, Team Deeply. Coral reefs are the epicenters of marine life, providing incalculable benefits and value to humanity. Climate change stands to wipe them out within our lifetime. The crisis facing the world’s coral reefs is now so dire that a recent gathering of experts desperately called for “” to save them.

Rapidly warming waters, combined with pollution and other stressors, is fast turning reefs from Florida to Australia into underwater graveyards, the bleached skeletons of corals standing as a grim testament to a changing climate. The trouble is, even proposed “radical” measures, including the spraying of seawater into the air to help form clouds that could temporarily cool waters, will likely not be enough at the scale we need it: Incidences of coral bleaching that once occurred occasionally are, according to a recent study, pushing reefs to the very brink of survival. Just like other animals on Earth, corals need a healthy habitat to survive. So, to protect them, we need to protect the places where they live. And marine protected areas, or MPAs – and other area-based approaches to reducing pressure from development, fishing and other impacts such as pollution – are proven to do just that. Thankfully, when MPAs are managed well and, they are effective at allowing marine life to thrive.

By scientists at Conservation International published in the journal Nature showed that the vast majority of protected areas improved fish stocks, and those that had adequate capacity, enforcement and funding delivered almost three times the beneficial ecological effects. The rise of new technology, meanwhile, has enabled us to greatly improve the ability to monitor MPAs remotely to enforce restrictions and identify illegal use. If the world’s coral reefs are to survive, we have to change the way we treat oceans and respond to the effects of climate change everywhere. To provide the best possible hedge against the confluence of stressors that are impacting reefs and the oceans overall, we need to be precautionary and protect as much as we can, as quickly as we can. A recent in the New York Times draws a needless distinction between large-scale and small-scale MPAs. It’s a false choice – the reality is that we need both. For too long, ocean conservation has been focused on drawing lines around the very smallest quanta of an ocean ecosystem: a single reef, a bay, a politically significant viewshed, but omitting critical surrounding areas that affect marine life within the MPA to be effective.

Moreover, nature knows no boundaries. Marine life shifts its range in response to climatic changes – including coral, albeit more slowly.

So the boundaries need to be big enough to provide protection for animals during all stages of life so they can adjust and continue to reproduce. Also, most MPAs don’t cover the high seas, waters that lie outside national jurisdictions. Several dozen seamounts that lie in international tropical waters may support coral reef habitats, including twilight coral reefs, so called because they thrive in deep waters where little sunlight penetrates.

Many of these open-ocean coral reefs have never been explored, and because they aren’t protected by the laws of any country, they are among the most vulnerable reefs on Earth. Before we even know the importance of these reefs as habitats for critical fisheries or as outposts for rare coral species, we may lose them.

So how do we address these challenges? We can start by making protected areas bigger. Large-scale marine protected areas (LSMPAs) – generally defined as marine conservation areas that are larger than 150,000 square km (58,000 square miles), about the size of the U.S. State of Georgia – offer a potential solution. Since 2000, more than 30 have been proposed or established within national waters by more than 15 countries. Compared with smaller areas, large-scale MPAs can provide more holistic protection – protecting entire ecosystems and providing a viable approach to protecting the high seas.

Given that the high seas cover more than 60 percent of the world’s oceans, it is critical that we change global policy, increase our scientific and management efforts, and strategically accelerate protection of this critical realm of the ocean. Lessons learned in large-scale MPAs that have been established in national waters provide us with the knowledge and experience we need to shape similar protections in the high seas. These large-scale MPAs don’t preclude protection of discrete areas of highly concentrated ocean life. They are a necessary complement.

Last year, the United Nations agreed to negotiate a binding, due by 2020. It’s a major step, but we can’t wait for the new treaty to be signed to take action. We must make additional investments – big and small – to protect our oceans now. For coral reefs, there is no time to lose.

Coral reefs technically do not move. Corals themselves are sessile creatures, meaning they are immobile and stationed to the same spot. They reproduce sexually, releasing eggs and sperm into the water, where baby corals are created before landing and settling. When corals die, they leave behind the hard calcium structure that comprised their bodies. As this layering process is repeated over and over, the coral reef expands and 'moves.' Some coral reefs are close to 100 feet thick. Coral Reefs & the Environment.
